Fords say cold when unplugged (ECT), find out what GM does, if it is opposite, it would lean out a fat mixture, either way, I would check the ECT first with an ohm meter if it is ok, go after the above.

i bought the $12 sensor that tells the comp. the temp but its still doing the same thing. i also took a can of carb cleaner and sprayed around the intake to see if it would suck anything up and idle faster momentarily while burning the carb cleaner and still found nothing...
